SPECIFICATION forming part of Letters Patent No. 777,107, dated December13, 1904,

Application filed December 29, 1903. Serial No. 187,006. (No model.)

To all wiz/1117, 1lb 'lita/y concern:

Be it known that l, HARRY KENYON, a citizen of the United States,residing at Maplepark, in the county of ,Kane and State of lllinoisdiaveinvented certain new and useful lmi'n'ovements in Grrinding-lvlachines;and I do herebyT declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to corn-crushing machinery, and more particular] yto that variety thereof designed to disintegrate earcorn, whereby thegrain will be shelled and the cob itself will be thoroughly divided intominute particles, thus fitting the same as a very desirable food forstock of all kinds; and my invention consists of certain novel featuresof construction and combination of parts, as will be hereinafter clearlyset forth, and pointed out in the claims.

The object of my invention, among' others, is to provide areliably-eliieient mechanism of the character specified, the parts ofwhich may be comparatively cheaply and expeditiously manufactured andassembled each in its rcspective operative place.

A further object of my invention is to provide mechanism which willprove ci'lieient in the grinding or crushing of ear-corn or grain uponthe stalk, thoroughly shredding the latter without the expensive anddangerous addition of a fly-wheel or balance-wheel to attain therequisite momentum of the cuttingor grinding parts.

A further object is to provide simple means to attain quick adjustmentof the cooperating cutting-teeth in order to compensate for wearthereof.

Other objects and advantages will be hereinafter made clearly apparent,reference being had to the accompanying drawings, which are made a partof this application, and in which-- Figure l is a perspective view of myinvention complete ready for use. lfig. Q is a top plan view of thecutting' part of my invention, showing a portion of the` hopper insection. Fig. 3 is a detail View showing a portion of the grinding orshredding cylinder in section and the relative arrangement Athereof tothe stationary cooperating parts or teeth. lfig. t is a sectional viewof Fig. 2 on line 2 2. Fig. 5 is a longitudinal section of thehopper,showing the revoluble grinding teeth or disks removed. Fig. 6 is aperspective viewshowing a portion of the hopper containing the adjustingmechanism carrying the reciprocating feeding' members or teeth. Fig. 7is a transverse section of the parts shown in Fig. G; and Fig. 8 is adetail view ofthe opposite end of the shaft to that shown in Fig. 3,showing the jam-nut to lock the disks thereon.

For convenienccin referring to the various details of my invention andaccessories deemed necessary to show a practical application thereof touse numerals will be employed, the same numeral referring to a similarpart throughout the several views.

Referring to the numerals on the drawings, land 2 designate end sectionsof the base, while 3 designates the side sections thereof, said partsbeing properly locked in coperative relationship, as by the bolts orscrews 1l. Suitable uprights or standards 5 are erected upon thebase-section thus constructed, and upon the upper end thereof theplatform members comprising the end sections (i and the side sections 7are secured and held together iii-any preferred way, as by the bolts 8,all of said parts being locked or reinforced in rigid relationship, asby the bracing members 9, as clearly shown .in Fig. l. Upon the supportthus constructed I mount the hopper of my grinding or shredding mill,which comprises the side members l0 and lll and the end sections l2, allof said parts being' properly secured together in any desired manner.rl`he inner surface of the hopper thus or otherwise constructed isproperly lined or faced, with metallic sheathing 13, and within thehopper l mount in suitable bearings .la the illrivingshaft l5,extending' entirely through each end of the hopper-section, and upon oneend of the shaft .l locate the driving-wheel .lo and i upon the otherend a sprocket or band wheel 17 for a purpose hereinafter made clear.

l desire to call particular attention to the construction of theinterior or grinding parts of the hopper, and, referring to Fig. i andother views, it will be observed that one endA of the shaft 15, uponwhich the driving-pulley l disk sections 21 of greatly larger diameter16 is mounted, is of slightly larger diameter than the other endthereof, the reduction in size of the shaft being indicated by thenumeral 18 in Fig. 3. The conical section 18 of the shaft is designed tolit the bore of the disk 19, which is designed to act as a shoulder orstop for other parts mounted on said shaft, as will be hereinafter madeclearly apparent.

Upon the reduced portion of thc shaft 15 I dispose a plurality ofcutting-disks 20, each disk havinga plurality of teeth and separated apreferably uniform distance from each other by the interposed diskmembers 21,the cutting'- disks 2O being of suitable hardened steel, aswill be obviously necessary, while the separatingmembers or disks 21 maybe of metal of any preferred character and each of proper thickness toseparate the cutting knives or disks 2O a sufficient distance to litbetween the stationary ribs or teeth 22, each of which is held uniformlyseparated to loosely receive the knives or teeth 20 by means ofinterposed blocks or plates 23. I also provide the end or clamping block24, havingI a slotted opening 25 to receive an anchoring-lug 26, carriedby a contiguous part of the frame-section, said block 24 being renderedadjustable by means of the set-screws 27, extending through the bracket28, and it is therefore obvious that since the clamping'- blocks 24 andset-screws 27 are duplicated at each end of the machine, as clearlyshown in Fig. 5, the position of the teeth or rib-sections 22 may bereadily adjusted to compensate for any change of position of therotating' cuttingteeth 20 and the interposed members 21. Upon the end ofthe shaft, opposite the member 19, 1 locate the jam-nut 29, it being'understood that the end of the shaft may be threaded at this point toreceive the same, and it therefore follows that after a full complementof cuttingdisks 2O and interposed separating-sections 21 are disposedupon the shaft 15 the jam-nut 29,will be turned home against the lastmember 21,and thereby firmly lock all of said parts upon said shaft. Itwill thus be seen that in the absence of the jam-nut 29 the cutting'-disks 2O would be left entirely loose upon the shaft- 15, but that whensaid nut is turned tightly h'ome said parts will be securely lockedtogether. This construction and combination of parts just described isdesigned to compensate for the sudden stopping of any one of thecutting-disks in case a bolt or other foreign substance should be placedin the hopper, inasmuch as it is clear that only the disk or disksengaging the bolt will be stopped thereby, while the others will bepermitted to rotate sufficiently to prevent the sudden stopping of themachine and the incident injury which would result. This construction isalso very desirable and important, inasmuch as it will permit anyinjured disk to be readily removed and replaced.

By providing the interposed members or than the shaft 15 it will be seenthatl provide what is substantially a heavy metal cylindrical shaft tocarry the plurality of knives, this increased diameter over the shaft 15being amply suflicient to com pensate for the absence of the fly-wheel,inasmuch as the momentum of a rapidly-rotating cylinder or shaft ofgreat size will provide sufficient impetus to carry the same through allordinary resistances incident to grinding a mass of ear-corn, fodder, orthe like.

ln mounting the plurality of interposed members 21 upon the shaft 15 Iprefer to key each alternate one or every second or third one of saidmembers to said shaft, as indicated by the numeral 30, whereby thestrain incident to a sudden stopping of the machine by an obstructionwill be taken off of the jamnut 29 and distributed throughout theplurality of keys 30, as will be obviously apparent.

It becomes desirable in order to insure a uniform feeding' of theear-corn to the plurality of cutting-knives 20 to provide suitablecooperating feeding devices, and with this purpose in view I provide aplurality of reciprocating teeth 31, which are carried by the bar 32,disposed parallel with the inner face of the hopper-section 11, as willbe more clearly seen in Figs. 2 and 5. The bar 32 is connected, by meansof the bolts 33, to the sliding blocks 34, which are designed to move inan adjustable frame, which comprises the angle-plates 35 and plates 36,properly secured together by being' connected to the stationary blocks37 and more clearly shown in Fig. 6. The bolts 33 are of suflic-ientlength to extend through the bar 38 upon the outside of thehopper-section, said bar being operatively connected with the pitman 39,which latter is attached at one end to the crank 40 upon the shaft 41,the lower end of said shaft being provided with a beveled gear 42, whichmeshes with a similar gear 43 upon the shaft 44, the latter being'mounted in suitable bearings upon the standards 5. The shaft 44 isdriven by means of the sprocket-wheel 45, which is placed in connectionwith the sprocket 17 by the sprocket chain 46 or other equivalent means,and it therefore follows that when the shaft 15 and the parts carriedthereby are rotated the shaft 44 will be turned and incidentallycommunicate motion to the shaft 41, thereby causing the reciprocation ofthe plurality of teeth 31.

inasmuch as it will become desirable at times to adjust the downwardreach of the teeth 31, I provide a threaded seat in the blocks 37 toreceive the end of the bolt 47, the upper end of which is passed looselythrough the plate 48, which latter is secured to the upper edge of thesection 11 of the hopper, the upper end of the bolt 47 being. square, asindicated by the numeral 49, whereby a wrench may be applied to rotatethe bolt in either direction and IOO IIO

IIS

incidentally raise or lower the block 37, and thereby carry the plates35 and 36 upward or downward, as desired, and incidentally adjust thepath of reciprocation of the blocks 3st. By this adjustability it istherefore obvious that lthe position of the teeth 3l relative to thefloor or bottom of the hopper may be readily attained, the oillice ofsaid teeth being, as hereinbelore stated, lto agitato the contents olfthe hopper at the point of reciproeation, whereby the ear-corn or thelike will be directed in the path of the teeth upon the grinding-disls-.lt will thus be seen that l have provided a very ei'iicient mechanismolf comparatively simple construction which will reliably perlorm theollice oi' breaking into small pieces ear-corn, or corn upon the cob,and that the grain will therefore be shelled from the cob and the latterthoroughly brolien into particles of proper size to constitute anexcellent variety ol food for stock.

l/Vhile the main use to which my machine may be placed will be that oi'grinding ear-l corn, it will also be desirable and useful for cutting orshredding fodder and the ear-corn carried thereby. Should by accident astone, piece of wood, bolt, or the like be introduced into the hopper,the rotation olf the shaitt l5 and. the teeth carried thereby will notbe instantly checked, inasmuch as the teeth are held only by lirictionalengagement arising from the pressure of the jam-nut, and when,therefore, more resistance is otlered to the rotating disks 2O than thatpresented by an oar of corn or a stall; oi' fodder said disks soobstructed will be held idle, while the momentum will carry thereinaining teeth in rotation until the machine is gradually stopped,thereby obviating the sudden strain and jar which might otherwise resultit all of said cuttingdisks 2l) were keyed rigidly to their shaft.

While l have described the preferred coinbination and construction ol'lparts deemed necessary in carrying out my invention, l desire to securesuch substantial equivalents and substitutes as may be regarded asfairly falling within the scope oi my invention.

Believing that the construction and manner oi using my invention havethus been made clearly apparent, lfurther description is deemedunnecessary.

Vllhat l claim as new, and desire to secure by .Letters `Patent, i`s---il. In a gx'inding-inill the combination with a hopper and a pluralityet cutting-disks rotatably mounted therein ol a feeding devicecomprising reciprocating' lingers, a bar on the inner side olI saidhopper, carrying said lingers, sliding blocks and means carried by saidhopper to secure said bar thereto, an adjustable Vframe to receive said.blocks, means to adjust said `l'frame vertically, a bar 3S on the outerside o'l said hopper, also secured to said blocks, a pitman pivotallysecured to one end ol" said bar 38, driving mechanism secured to theopposite end olf said pitlnan and means to actuate said mechanismwhereby said lingers will be rceiprocated, as set forth.
